In this frame grab provided by KWTV is one of many tiny red worms that workers in Colcord, Okla., found in a filtering system for the town's drinking water. Residents were asked to not drink tap water after the worms _ ranging from a half-inch to an inch long _ showed up earlier this week. A spokesman said city water was turned back on Wednesday, Aug. 28, 2013, after workers cleaned, drained and re-cleaned the town's water tower.
